摘要
Abstract
The existing static safety sensitivity techniques are all applied to analyze the impact of one single branch on the power flow of another branch.In this paper,a sensitivity technique is studied,with which the impact of simultane-ous tripping of multiple branches on the power flow of one single branch is analyzed.First,the calculation of sensitivity factors for multiple branches is converted into the calculation of sensitivity factors for one single branch under some spe-cific grid structures,and it is further extended to scenarios of 220 kV bus and 500 kV bus tripping.The obtained sensi-tivity factors have a clear physical meaning and low computational complexity.Second,for the convenience of cross-sec-tion control,the concept of cross-section sensitivity factor and its calculation method are proposed,which has a clear physical meaning and simple calculation.Finally,the simplicity of the proposed sensitivity algorithm and the accuracy of power flow control are verified through numerical examples.关键词
